Add Duplicate Node Names Validator

[pedroigorjs]

This pull request introduces a new validator to ensure node names are unique within a graph and adds comprehensive test coverage for this validation. The main changes include the implementation of the validator, a new invalid test resource, and an additional test case.

Validation logic:

• Added UniqueNodeNameValidator in unique_node_name.py to check that all node names (excluding "Input" and "Output") are unique within the graph, returning a detailed error message if duplicates are found.

Testing:

• Added a new invalid graph resource duplicate-node-names.json containing nodes with duplicate names to test the validator.
• Extended the test suite in test_executor.py to include a case that expects a duplicate node name error when processing the new resource.
